In latest BFBlender CVS, when selecting a mesh with RVK parented to an armature, both sets of keyframes (action and RVK) are displayed together in a rather confusing way (RVK on top of bones keyframes).

Though ithis might be useful to synchro action with facial animation, it is indeed a little confusing... I spent 1 minute trying to figure out why I couldn't select a keyframe till I realized it was a bone keyframe and I had the mesh selected (thus, only RVK keyframes available for editing) duh !

Is this a new feature or just a bug ?

If a feature, it could be improved by changing colour of "top/below layers" of keyframes to quickly recognize which is which.
